FireFox update

Firefox users who cannot wait to update the stable channel of the web browser from version 11 to 12, can download the new version from the official Mozilla ftp server or third party download sites early. Please note that while it is unlikely that the final version will get replaced in last minute, it has happened in the past. It is recommended to wait for the official release announcement if Firefox is running in a productive environment, or if you do not need to have access to the new feature set introduced in the browser right away.

The majority of features are only interesting for web developers and developers in general. Firefox 12 supports the CSS text-size-adjust property, and the outerHTML property. Developers can furthermore make use of the Style Editor for editing CSS, and the new Page Inspector 3D View which is available if the computer is compatible with WebGL.Firefox 11 furthermore supports the SPDY protocol for faster page loads, and XMLHttpRequest HTML parsing.The change log lists unresolved issues, among them some that have been noticed by some users in previous versions of the browser as well. This includes the slow scrolling in the Gmail window, or jerky scrolling and text input under certain conditions.It is not really necessary to update the browser right now, instead of waiting the three days before the official announcement is being made. It would be different if stability or security updates were included in the release.

It's official! Firefox 12 is available here: Mozilla Firefox Web Browser

I got mine a couple of days ago from File Hippo. Upon startup, it checks for updates & offers to display them, if any. Great little program to have, it keeps on up to date with FF & other browsers, Java, Flash & many others.

Firefox 13 is out and available at the link below.

Today’s preview marks the beginning of Mozilla community testing for the Firefox Metro browser designed from the ground up for Windows 8.

As the above say's Mozilla is ready for you to try the Metro version of Firefox:

The preview includes a new Metro style Firefox Start page, support for Firefox Sync, Metro touch and swipe gestures, integration with Windows 8 “charms”, and a simple but powerful Australis interface that is streamlined, modern, and beautiful. Over the coming weeks and months, we’ll be adding more features, tightening up Windows integration, improving performance and responsiveness, and finishing up all the necessary work to deliver a first class Firefox experience for Windows 8.

This is an early preview and we know there are bugs and missing features, so please don’t hesitate to share your feedback and file any bugs you find. Stay tuned to this channel for further updates.
